Abstract

A cable connector is provided for coupling to and mounted within the internal cavity of an electrical box for securing an electrical cable passing through an opening in the electrical box. The cable connector includes a body having a first end positioned next to or adjacent the cable opening in the electrical box and a second end spaced from the first end and the cable opening. At least one and typically two retaining members are spring biased from the first end of the body and extend into a cable passage of the body toward the second end. A front wall is provided at the second end of the body with an opening for receiving the wires and forming a stop member to prevent the armor sheathing from passing through the front wall.

First claim

What is claimed is:

1. An electrical box assembly comprising:
an electrical box having an internal cavity, a rear wall, and a side wall with a cable opening having a dimension for receiving an electrical cable; and
a cable connector fixed to said electrical box completely within said internal cavity, said cable connector having a cable passage aligned with said cable opening in said side wall, said cable connector having a body with a first end positioned adjacent to the cable opening on an inner face of the electrical box and a second end opposite the first end and spaced inwardly from said side wall;
a front wall at said second end of said body and having an opening for receiving the electrical cable, said opening in said front wail having a dimension so that said front wall abuts the metal sheath of a standard metal sheath cable with a plurality of conductors to allow the conductors of the cable to pass through the opening and prevent the metal sheath from passing through the opening;
a first cable retainer having a first end at the first end of the body and a second free end extending toward the front wall, said free end of said first cable retainer extending toward the front wall and towards an axis of the cable passage for gripping a cable and capturing the cable between the second free end and the rear wall of the electrical box; and
a second cable retainer having a first end at said first end of said body and a second free end extending toward the front wall, said free end of said second cable retainer extending toward said front wall and toward the axis of the cable passage.

2. The electrical box assembly of claim 1 , wherein said cable connector further comprises
a first side wall on a first side of said cable passage, said first end of said first cable retainer extends from a first end of the first side wall, and a second side wall opposite said first side wall on a second side of said cable passage and having said second cable retainer with a first end coupled to and extending from a first end of said second wall and a second free end extending toward said front wall and toward the axis of the cable passage.

3. The electrical box assembly of claim 2 , wherein
said first cable retainer is integrally formed with said first side wall and said second cable retainer is integrally formed with said second side wall.

4. The electrical box assembly of claim 2 , wherein
said first cable retainer is coupled to said first side wall by a U-shaped portion to spring bias said first cable retainer inwardly toward the cable passage, and said second cable retainer is coupled to said second side wall by a U-shaped portion to spring bias said second cable retainer inwardly toward said cable passage.

5. The electrical box assembly of claim 1 , wherein
said body has a bottom wall extending between said first end and second end, and where said first cable retainer and said second cable retainer are coupled to said bottom wall.

6. The electrical box assembly of claim 1 , further comprising
a leg positioned between said first cable retainer and said second cable retainer, said leg having a first end coupled to said first end of said body and a second free end extending into said cable passage and being configured to grip the electrical cable.

7. The electrical box assembly of claim 6 , further comprising
a rear wall at said first end of said body and oriented substantially parallel to said front wall and having an opening therein aligned with said cable passage for receiving the electrical cable, and where said leg is coupled to said rear wall and extends toward said front wall between said first cable retainer and said second cable retainer.

8. The electrical box assembly of claim 7 , wherein
said first and second cable retainers are coupled to said rear wall of said cable connector.

9. The electrical box assembly of claim 1 , wherein said cable connector further comprises
a top wall at said first end of said body and extending between said first end and said second end;
a leg coupled to said top wall at said first and an extending toward said front wall and toward the axis of the cable passage and being configured to engage a top surface of the cable.

10. The electrical assembly of claim 9 , wherein
said first and second cable retainers are coupled to said top wall.

11. An electrical cable connector for clamping at least one electrical cable extending through a cable opening in an electrical box, said cable connector comprising:
a body having a cable passage, said body having a flange, configured for coupling to a bottom wall of the electrical box and having a first end for positioning in the electrical box adjacent the cable opening within the electrical box and a second end opposite said first end within the electrical box, said body having a first side wall with a first end and a second side wall with a first end, a top wall extending between said first side wall and said second side wall, and an open bottom opposite said top wall;
a front wall at said second end of said body and having an aperture for receiving the at least one electrical cable, said aperture having a dimension so that said front wall abuts the metal sheath of a standard metal sheath cable having a plurality of conductors to allow the conductors of the metal sheath cable to pass through said aperture and prevent the metal sheath from passing through the aperture;
a first cable retainer having a first end coupled to and extending from said first end of said body and a second free end for gripping first side of the electrical cable, said first cable retainer being integrally formed with said first end of said first side wall; and
a second cable retainer having a first end coupled to and extending from said first end of said body and a second free end for gripping a second side of the electrical cable, and said second cable retainer being integrally formed with said first end of said second side wall.

12. The electrical cable connector of claim 11 , wherein
said first cable retainer is coupled to said first side wall by a spring U-shaped portion, and where said first cable retainer has a first leg portion extending from said first and toward said cable passage and a second leg portion extending from said first leg toward said cable passage;
said second cable retainer is coupled to said second side wall by a spring U-shaped portion, and where said second cable retainer has a first leg portion extending from said first and toward said cable passage and a second leg portion coupled to and extending from said first leg portion toward said cable passage.

13. The electrical cable connector of claim 12 , further comprising
a rear wall at said first end of said body and having an opening for receiving the electrical cable; and
a leg coupled to said rear wall and extending toward said front wall between said first cable retainer and said second cable retainer and extending toward the axis of said cable passage.

14. The electrical cable connector of claim 11 , wherein said body further comprises
a rear wall at said first end of said body, said first cable retainer and second cable retainer being coupled to said rear wall; and
a leg coupled to said rear wall and extending toward said front wall between said first cable retainer and said second cable retainer and extending toward the axis of said cable passage.

15. The electrical cable connector of claim 11 , wherein said body further comprises
a top wall extending between said first end and said second end of said body;
a rear wall at said first end of said body and where said first ca
